Most magics are of the 'speak word, do magic' type.
Eragon (Inheritance Cycle) - same thing, though with the addition of magic = natural strength, which makes doing thinking through spells and phrasing them important. Like, a spell for killing someone by severing neurons, rather than choking them. A pretty well fleshed out system, though plenty of vagueness as well.
Drizzt / Forgotten Realms / D&D : Memorize spell, speak words, magic.
i still think that most are anagogic-type sorcery. Want fire? Speak Fire/dragon breath/etc.
